Abstract: Duchenne muscular dystrophy (DMD) is an X-linked recessive neuromuscular disorder, and the carriers of DMD can suffer from cardiac damage without muscle weakness, which can predispose to death. Consequently detecting and preventing cardiac damage in the early stage can improve the carriers' quality of life. The detection of early cardiac abnormalities and the evaluation of cardiac function for carriers mainly rely on the different examination methods, including electrocardiogram, echocardiogram, cardiovascular magnetic resonance, radioactive nuclide myocardial perfusion imaging and coronary angiography. Carriers of DMD with cardiac damage are assessed by different examination methods in different ways.
